Constructor Details

CMapToUnicode

             public CMapToUnicode()
            

Creates a new instance of CMap.

Method Details

getIdentity

             public static CMapToUnicode getIdentity()
            

createToUnicodeCmap

             public static CMapToUnicode createToUnicodeCmap
             (FontEncoding fontEncoding)
            

Creates a ToUnicode CMap from the given font encoding.

Parameters:

fontEncoding - the font encoding

Returns:

the ToUnicode CMap

hasByteMappings

             public boolean hasByteMappings()
            

This will tell if this cmap has any two byte mappings.

Returns:

true If there are any two byte mappings, false otherwise

lookup

             public char[] lookup
             (byte[] code, int offset, int length)
            

This will perform a lookup into the map.

Parameters:

code - the code used to lookup

offset - the offset into the byte array

length - the length of the data we are getting

Returns:

the string that matches the lookup

lookup

             public char[] lookup
             (byte[] code)
            

lookup

             public char[] lookup
             (int code)
            

getCodes

             public Set<Integer> getCodes()
            

createDirectMapping

             public com.itextpdf.io.util.IntHashtable createDirectMapping()
            

createReverseMapping

             public Map<Integer,Integer> createReverseMapping()
            

getCodeSpaceRanges

             public List getCodeSpaceRanges()
            

Returns a list containing sequential pairs of code space beginning and endings: (begincodespacerange1, endcodespacerange1, begincodespacerange2, endcodespacerange1, ...)

Returns:

list of byte[] that contain code space ranges
